Title: Driving system of pulse motor
Inventor: SATOU KAZUYASU
IPC: H02P8/36
Filed: 1979-08-21
Abstract: PURPOSE:To prevent the peak current of the pulse motor and to contrive the reduction in size of the pulse motor driving system by providing the first loop circuit including an energization phase switching transistor and an excitation coil and the second loop circuit including an excitation coil and an electric power consuming circuit. CONSTITUTION:A diode 7 is connected between one end of the excitation coil 2' of a pulse motor and one end of a phase switching transistor 4' to form the first loop, and a series circuit of a diode 1' and a zener diode 5' is connected across an excitation coil 2' to form the second loop for consuming an electric power. A transistor 9 is connected between a power source terminal 8 and the excitation coil 2', and is operated on or off to thereby control an excitation current. Accordingly, when the drive signal of the transistor is shortened as compared with a phase excitation signal, the peak current can be resultantly prevented at the time of switching the phase, and the capacity of the circuit element can be consequently reduced by utilizing the phase energization with the loop current.

IPC: C02F1/58
Filed: 1979-08-21
Abstract: PURPOSE: To enable to decompose hydrogen peroxide contained in an exhaust water of a factory used in a washing liquid of a semiconductive substrate plate in an accelerated speed by using a decomposition promoting agent an iron material and a copper material.  
     CONSTITUTION: An exhaust water of a factory containing hydrogen peroxide is stayed in a decomposition tank and, as a decomposition promoting agent, an iron and a copper material are thrown into the decomposition tank to promote the decomposition of hydrogen peroxide. A thrown-in amount is 30kg as copper trashes and 70kg as iron trashes against 1,000m 3  of an exhaust water and this amount is practically sufficient. Moreover, by said method, the decomposition speed can be enhanced by changing the throwing ratio of coppers and irons without changing the wt. of a decomposition promoting agent.

Abstract: PURPOSE:To enable excuting effective phase compensation and wave form equalization of a regenerative wave form with a simple circuit constitution by performing an adding procession of a differentially processed signal and a signal before the differential procession after a regenerative signal having a non-symmetrical distortion respect to the plane of symmetry is square arithmatic-processed. CONSTITUTION:The outputted regenerative signal of a rotary head 7 is amplified by a regeneration amplifier 8 and a regenerative signal after an equalization whose differential characteristic of an electromagnetic conversion system is compensated by an equalization circuit 9 is square arithmatic-processed and outputted by a square processing circuit 10. A differentiation circuit 11 rotates vertical/longitudianal orientated angles included in the regenerative signal outputted from the circuit 10 by pi/2 equivalently and outputs it to an addition ratio adjusting circuit 12. An addition circuit 13 adds an output which is outputted by the circuit 12 and whose addition ratio is adjusted so that the output of the circuit 11 has a minimum non-linear distortion of the regenerative wave form by the circuit 12 and the output of the cirucit 10 to be outputted. A peak detecting circuit 14 detects data by detecting the peak of a wave form having no non-linear distortion outputted from the circuit 13. Thus, the phase compensation and wave equalization are performed effectively with a simple circuit constitution.
